METHOD FOR PRODUCING trans, trans-MUCONIC ACID OR ALKYL ESTER THEREOF

摘要

Trans,trans-muconic acid or an alkyl ester thereof, which serves as a raw material for terephthalic acid or an alkyl ester thereof, is produced by a step in which α-hydromuconic acid or an alkyl ester thereof, which can be derived from biomass resources, is dehydrogenated in the presence of a dehydrogenation catalyst.
